I am using the credit from this purchase towards the Panasonic 65 inch GT30. I was told to expect them in Mid-May. Does anyone have any different information?
Not to go off topic but 2011 Samsungs have floating black levels?

Can anyone confirm this?

The error seems to lie with the report of the initial reading (1.1) but 1.9 still stands.
post #123 of 4163
Correct, I read on HDJ that their intial Gamma reading was incorrect. It appears that the reading was actually 1.9 (still a little bright I know), but until a proper review is done on the set, I will withhold judgement.

I've already read the reviews from calibrators and sure they have some nice things to say but the tone on their posts/reviews is of dissapointment. Look i know you guys like panasonic and I do to but c'mon, you can't really sit there and tell me that the GT30 is a superior product. If this was LG or some of those other cheap brands, it would be acceptable. But when your known for making one of the best plasmas in the market and you advertise as so, then its unacceptable. If anything you guys are misinforming people with your blind nuthuggery of panasonic.
I'm sorry, but you are going off a bit half-cocked here. The person who wrote that HDJ report has said explicitly that he's very confident the gamma measurement was flawed. In fact, they're pretty sure it came from the calibrator just mistakenly measuring 90 IRE twice instead of 90 and then 100. This sort of error happens all the time in calibrations, especially when they're pressed for time.

The misinformation here is from you, not from the other participants.

Me too.

Not quite completely true.

Larry what set is that measurment for and who took the measurement?

Simply posting a graph hardly supports much of anything.

What sets did Panasonic release that had 2.2 gamma in THX right out of the box?

It clearly states on the graph that it is an X1. I took the measurement using my i1 LT profiled to my certified i1 Pro. The calibration was performed in May 2010. I check the calibration about once a year.

If you search through my posts you will find the results of many calibrations that I have performed.



EDIT: Here is the calibration report for the X1 by D-Nice: http://www.avsforum.com/avs-vb/showt...3#post16014003

For those who don't know how to read the report, I've attached his gamma results going from 0 to 100% stimulus.

did any body test the gt30's 3D yet?? and is it just as good or better then last years VT series and how does it compare to the D series samy 3d wise thanks

I also measured 1.9 on the GT30 O have.

Thank you. I don't know how I overlooked the X1 at the bottom there but I did. I appreciate your response.

D-Nice,

Even though you will not be posting service menu offsets this year (I understand why,) I hope that you will post a calibration report showing the best grayscale tracking that you can get with the G30 using the SM.

That's all well and good if you consider 2.2 to be accurate gamma.

Well for a set without a gamma control, what do you expect? Magic?

No. I'm just saying none of their plasmas have correct gamma for viewing under dim lighting conditions, which is what plasma is intended for.

Okay! Please don't talk down to me. I probably know more about gamma than you realize.

Enough with gamma and Panasonic. You can't get what you want from their models so why harp on it?

If you know all about gamma then you would understand why 2.2 is incorrect for a dim surround.

I'm not harping on anything. You asked a question, I answered it.
post #137 of 4163
So what's going on with this tv? Why didn't the first reviews mention the abysmal out-of-the-box 1.1 Gamma? Is is possible D-Nice's set was defective? I find it really hard to believe that Panasonic would ship a TV series that starts at $1,900 with such a huge flaw.

+1 as I never measured 1.1 on a GT30.

I guess that you still don't understand. When a TV has no gamma control, there is no control over gamma.

The X1 has no gamma control. What I posted it is what it is. Would I like it different gamma for my environment? Maybe but there is nothing I can do about it with this set. Would I want a gamma of 2.4 or greater? Probably not. Understand now?

I was going to post something about how senkoskipper probably should have his heresay privaledges taken away considering the only thing defective was the way the measurement was conducted on one review, and that taking it upon himself to inform everyone else here that every panasonic set except the ST30 was "defective" this year warrants a "durrrrrrrpppp" award, but it seems like others have already done that :P .

The exception would be if D-Nice says he can get it up to standard and that anyone else could as well.

....Unless the THX mode got worse since 2008 (and I imagine it didnt since I would think part of the point is to keep the settings relatively consistent), I very much disagree with this statement. I need to get an additional set to supplement my 2008 model when they first started using THX and I think it's a great mode, and it looking great out of the box (yeah I tried a few tweaks to make it look a little different, perhaps slightly brighter possibly I think), is one of the reasons I gravitated toward that model, as well as getting a panasonic again. I movie watch and game in that mode and it looks pretty damn good to me, and I look forward to supplementiong it with 3 years of TV improvements to boot.

still a little bright??? But all the complaints were that the THX mode was too dim (although I remember hearing this from 2008 as well, people just needed to get used to the comparative difference between that and a vivid mode I felt).

You can set you gamma to 100. I don't give a damn. If you understood Poynton, you would understand me.

Good bye,

D-nice is reporting, in another forum, serious brightness fluctuations with the GT30 that in his words are worse than how the ST30 behaves.

This is strange and I don't know if he has a bad display because they specifically looked for floating blacks and luminance shifts at VE when they compared the ST30, GT30 and D8000 and reported they could not see this behavior.

I wouldn't count on that review for your information. I'm not slighting those who were there, I'm just saying that it was a casual review. I thought I saw it fluctuation in the third video.

Read flatpanelshd's review and read it carefully.

THX mode on this set is not as good as the one on my G25. I don't know what was going on with gamma in past sets but this one isn't good. 1.9 gamma, 1.9 out of the box. Do you understand what that means?

A little bright doesn't mean the picture is bright, it means it's rising out of black too fast.
post #150 of 4163
I forgot to ask you Spincut, are 1.9 gamma and floating whites (post calibration and worse than in the ST30) acceptable to you in the second best tv? Would you say that those factors are acceptable on a THX certified set?
